Variants

Tuple(usize)

The tuple of the given arity.

Str

str, which is a struct containing a [u8] the standard library expects to be valid UTF-8.

Closure

A closure.

Use

A use declaration.

AnonConst

An anonymous constant.

PromotedConst

A constant that rustc promoted out of a body.

ClosureAsFn

The function item we generate for a closure that is cast to a function pointer.

DropGlue

The method we add to the Destruct trait to hold the drop glue.

VTable

The vtable struct of a trait, or the vtable global of a trait impl.

VTableMethod

The version of a method that is stored in a vtable.

VTableDropShim

The drop_in_place shim stored in a vtable.

impl BuiltinPathElem

pub fn is_rust_name(self) -> bool

pub fn ident(self) -> &'static str

The identifier we use to refer to this element.

Trait Implementations

impl AstVisitable for BuiltinPathElem

where BuiltinPathElem: PartialEq,

fn drive<V: VisitAst>(&self, v: &mut V) -> ControlFlow<V::Break>

fn drive_mut<V: VisitAstMut>(&mut self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_two<V: ZipAst>(&self, other: &Self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn name(&self) -> &'static str

The name of the type, used for debug logging.

fn dyn_visit<T: AstVisitable>(&self, f: impl FnMut(&T))

where Self: Sized,

Visit all occurrences of that type inside self, in pre-order traversal.

where Self: Sized,

Visit all occurrences of that type inside self, in pre-order traversal.

impl BodyVisitable for BuiltinPathElem

fn drive_body<V: VisitBody>(&self, v: &mut V) -> ControlFlow<V::Break>
